// Camera - SX20 - platform_camera.h

// This file contains the various settings values specific to the SX20 camera.
// This file is referenced via the 'include/camera.h' file and should not be loaded directly.

// If adding a new settings value put a suitable default in 'include/camera.h',
// along with documentation on what the setting does and how to determine the correct value.
// If the setting should not have a default value then add it in 'include/camera.h'
// using the '#undef' directive along with appropriate documentation.

// Override any default values with your camera specific values in this file. Try and avoid
// having override values that are the same as the default value.

// When overriding a setting value there are two cases:
// 1. If removing the value, because it does not apply to your camera, use the '#undef' directive.
// 2. If changing the value it is best to use an '#undef' directive to remove the default value
//    followed by a '#define' to set the new value.

// When porting CHDK to a new camera, check the documentation in 'include/camera.h'
// for information on each setting. If the default values are correct for your camera then
// don't override them again in here.
